SealFit

SealFit is similar to CrossFit, even including some CF workouts within their own. Unlike Crossfit, SealFit doesn’t just try to get you in and out of the gym. Workouts take longer and focus on several different areas.  Base fitness (or warm up), pure strength, durability and work-capacity. With exercises for each category, this can be a really strenuous routine if you don't scale it to yourself.  Even then, it should be fairly difficult, but for those of you that like to lift and feel better when you spend 45 minutes to an hour in the gym, this might be a better fit than Crossfit.
